Speoiilcation of Letters Patent. Patented Aug, 17, 1920.

fApplieation nled February 19. 1917. Serial No. 149.536.

Omaha, in the county of Douglas and tate 'of Nebraska, have invented new and useful Improvements in Exhausters, of which the following is a full, clear, concise, and exact description, reference bein had to the aocompanying drawing, formlng a part of this specification.

My invention relates to a conveying and heating machine for canned goods.

One of the objects of m invention is to provide such a machine whlch will be simple and compact in construction and rapid and efficient in operation.

Further objects will a pear from the detailed description to follow and from the appended claims.

In the drawings, in which one form of my invention is shown:

Figure 1 is a perspective view of a conve ing and heating machine, known as an ex auster, embodylng my invention;

Fig. 2 is a side elevation of the u per portion of the machine showing part o the drive mechanism;

Fig. 3 is a plan view of part of the machine, showing the arrangement of the conve er rolls and heating. pipes;

ig. 4 is aside elevation of the end of one of the conveyer rolls;

Fig. 5 is an end elevation of Fig. 4;

Referring now to the drawings in detail,

the exhauster shown com rises a heating chamber 10, a plurality o steam pipes 11, for heating the chamber 10, a plurality of rotatable, horizontal, parallel conveyer-rolls 12 for causing the canned in a tortuous path throng the heating chamber 10, Vdriving mechanism 13 for the conveyer rolls 12, and a base or supporting frame 14 for supporting the various parts of the machine.

The heating chamber 10 comprises a rectangular frame 15 having openings 16 and 17 for the entrance and exit of the cans and a cover 18 for preventin the escape of steam from the heating -chamen The heating chamber may also be provided with bale walls 19 and 20, for hindering the escape of steam through'the openings 16 and 17.

Each conveyer 12 comprises a hollow c lindrical portion 21 on which the end of t e can rests as it travels, a helical cam por,

oods to move.-

i tion 22 secured to the cylindrical portion 21, which engages the can and pushes it nalong as the conveyer roll rotates, and journal members 23 and 24 to which the ends of the cylindrical portion 21 are secured, which journal portions are mountedl in suitable bearings on the frame 14.

The helical cam portions 22 are wound in opposite directions on adjacent rolls (Fig. 3). The rolls are all caused to rotate in the same direction by means of a chain 25 driven Y from the pulley 26,v the upper run of which chain engages with sprockets 27 to which the conveyer rolls 12 are secured in such manner as to rotate therewith.

For supporting the cylindrical cans with their axes in upright position as they are moved along by the conveyer rolls, horizontal tracks or supports, 28 are provided alongside the conveyer rolls, on which the bottoms of thecans may rest as they are pushed along.

For latteral y ol' of the rolls, and also for heating the contents of the cans, a ertured steam pipes 29 are provided alongsi e of and intermediate the conveyer rolls '12,' againstwhich pipes the sides 'of the cans may bear as they are moved along by the conveyer rolls.

. These pipes 29 are supplied with steam from headers 30 which extend along the ends of nates' short of the end of the adjacent conveyer rolls. This construction and arrangement of the heating pipe forms a. tortuous Egthror tlf cans through the heating chamr 1g. A

For transferring the cans from one roll 12 to the next, after they have traveled the length of the roll, each roll is provided at. one end with a cam portion 309, which is so positioned and proportioned that as the helical cam 22 moves the can alon 'toward theend of the roll, the cam 30 wi engage the can and push it over onto the succeeding roll 12.

The face 31 of the cam 30'L which engages the can is curved back (Fig. 5) and so shaped that it will not dig into the cans as it is shoving them overonto the succeeding roll. This cam 30, if desired, may be formed integral with the journal member 24. The headers 30 are engaged by the cans as reventing the cans from slipping i they are being shoved from one roll to the other and guide the cans in their movement. A suitable support 3()h is provided on which the bottoms of the cans rest as they are being transferred from one roll to the next.

Any suitable mechanisms 32 and 33 respectively may be provided for supplying the cans to, and removing them from, the heating chamber 10.

The operation of the machine is as follows: The cover 18 of the heating chamber is closed, steam is turned into the headers and the pipes 29, and power is applied to the pulley 26, to cause the rotation of the conveyer rolls l2 through the chain 25 and sockets 27. The filled cans are supplied one at a time through the opening 16 by means of the supply mechanism 32. As the cans are placed one at a time on the first conveyer roll 12 they are engaged by the helical cam portion 22 and forced to travel lengthwise on the rolls 12. The bottoms of the cans as they travel along rest on the guides or supports 28 and the cans'are prevented from being forced off laterally from the conveyer rolls by their engagement with the heating pipes 29.

The frictional engagement between the sides of the cans and the heating pipes 29 as the cans are moved along results in a rotation of the cans about their own axes; thus in Fig. 3 if the rolls 12 are rotated in the direction indicated by the arrows A, they will shove the can over against the steam pipe 29 to the left of the rollers and as the cans are forced along with their sides in engagement with the pipes 29, they'will be given a rotationv about their own axes.

When a can comes to the end of the roll on which it is traveling, it is engaged by the cam surface 31, and pushed over onto the succeeding roll and engaged by the helical cam 22 of the succeeding roll, which is wound in an opposite direction to that of the preceding roll. Thus the cans travel back and forth through the heating chamber and are transferred from one roll to the next until they are forced out through the opening 17, and removed by the mechanisln 33.

The rotation of the cans about their own axes resultsin bringing different portions of the cans in contact with the heating pipes 29 causing a rapid heating of the contents of the can, and lessening the time required for suiiciently heating the canned j goods.

Having thus described my invention, what I claim as new andl desire to secure. by Letters Patent, is '1.
